Hydraulic Support Cylinder Introduction
A Hydraulic Support Cylinder (also called a hydraulic work support) is an industrial component that uses hydraulic oil as power to provide workpiece support and prevent deformation. Its primary function is not clamping, but support and positioning, ensuring that during machining the workpiece does not vibrate, deform, or sink due to cutting force or gravity.

Key Features
1. Automatic Support: The piston rod is driven by hydraulic pressure to extend and support the required position of the workpiece.
2. High Rigidity: Internal design allows it to withstand large cutting loads, ensuring stability during machining.
3. Vibration and Deformation Prevention: Especially effective for thin plates, long workpieces, or thin-walled components.
4. Automation Application: Can be integrated with CNC machining centers, jigs, and fixtures to improve machining stability and accuracy.
5. Operating Types: Spring-advance type and hydraulic-advance type.
6. Mounting Type: External thread mounting with a mounting base.

Application Examples
1. Thin-Wall Workpiece Machining: In CNC milling of aluminum housings, where the thin walls are prone to deformation, hydraulic support cylinders are installed at the bottom or sides. During cutting, the support cylinder automatically props up weak sections to prevent vibration and bending.
2. Long Workpiece Machining: When machining long steel plates or aluminum extrusions, the middle section often sags due to gravity. Installing a hydraulic support cylinder at the center distributes the load evenly, ensuring cutting precision.
3. Mold Machining: During high-speed milling of molds or castings, localized structures can bend under cutting forces. Hydraulic support cylinders provide extra support, reducing machining errors.
4. Automated Fixtures: In automated jig and fixture systems, the support cylinder automatically extends after workpiece positioning. Used together with hydraulic clamps, it enhances the reliability of workpiece fixation.

Simple Concept
Hydraulic Clamp (for holding the workpiece) + Hydraulic Support Cylinder (for supporting weak points) → Together form a complete workholding system, ensuring machining precision and preventing workpiece deformation.
